Chapter 37 Circulatory System notes

The human circulatory system consists of the heart, a series of blood vessels and the blood that flows through them.
Your heart is located hear the center of your chest. It is composed almost entirely of muscle. The hard is enclosed in protective tissue called pericaridum. In the walls of the heart there are two thin layers of epithelial and connective tissue that form a sandwich around a thick layer of muscle called the myocardium. The powerful contractions of the myocardium pump blood through the circulatory. Dividing the right side of the heart from the left side is the septum or wall. The septum prevents the mixing of oxygen-poor and oxygen rich blood. On each side of the septum are two chambers. The upper chamber which receives the blood is called the atrium. The lower chamber which pumps blood out of the heart is the ventricle.
The heart functions as two separate pumps . The right side of the heart pumps blood from the heart to the lungs. The left side pumps out of the lungs and into the left side and then out to the body. This pathway is called systemic circulation. Blood that returns to the right side of the heart is oxygen poor because cells have absorbed much of the oxygen and loaded the blood with carbon dioxide. t this point, it is ready for another trip to the lungs.
As blood flows through the circulatory system, ti moves through three types of blood vessels - arteries, capillaries, and veins.
Red blood cells transport oxygen. They get their color from Hemoglobin. It is the iron containing protein that binds to oxygen in the lungs and transports it to tissues throughout the body where oxygen is released.
White blood cells, or leukcocytes are fewer than red blood cells. For every 700 red blood cells, there is just one white blood cell. White blood cells attack foreign substances or organisms.
Blood clotting is made possible by plasma proteins and cell fragments called platelets. There are certain large cells in bone marrow that bread into thousands of small pieces. Each fragment of cytoplasms is enclosed in a piece of cell membrane and released into the bloodstream as a platelet.
A network of vessels called the lymphatic system collects the fluid that is lost by the blood and returns it to the circulatory system. The fluid is called lymph. It collects in lymphatic capillaries and slowly flows into larger and larger lymph vessels. Like large veins, lymph vessels contain valves that prevent lymph from flowing backward. Ducts collect the lymph and return it to the circulatory system through two openings in the superior vena cava. The openings are under the left and right clavicle bones just below the shoulders.

Muscles! Chapter 36-2 Notes

More than 40% of the body's mass is muscle. There are three types of muscle tissue - skeletal, smooth and cardiac. Each one has a different structure/purpose.
Skeletal muscles are usually attacked to bones. They are responsible for voluntary movements. It is also called striated muscle. Most of them are controlled by the central nervous system.
Skeletal muscles are long and thin. Smooth muscles are usually not under voluntary control. Cardiac muscle is found in the heart.
A muscle contracts when the thin filaments in the muscle fiber slide over thick filaments.
The energy for muscle contraction is supplied by ATP.

Core Bio Notes Chapter 36-1

The skeleton supports the body, protects internal organs, provides for movement, stores mineral reserves, and provides a site for blood cell formation.
The skeleton is like the wooden frame of a house.
Bones also protect the internal organs of the body. For example, the skull protects the brain, and the ribs protect the lungs.
They are also a system of levers that control muscles.
Bones are also the site of blood cell formation.
Blood cells are produced in soft marrow tissue that fills the internal cavities in some bones.
There are 206 bones in the adult human skeleton.
The bones can be divided into two parts, the axial skeleton and the appendicular skeleton. The axial skeleton supports the central axis of the body. It consists of a skull, the vertebral column and the rib cage. The bones of the arms and legs along with the bones of the pelvis and shoulder area, from the appendicular skeleton.
Bones are a solid network of living cells and protein fibers that are surrounded by deposits of calcium salts. The bone is surrounded by a tough layer of connective tissue called the periosteum. Blood vessels that pass through the periosteum carry oxygen and nutrients to the bone. Beneath the periosteum is compact bone. It is dense and within it runs tubes called Haversian canals. They contain blood vessels and nerves. Underneath that is the spongy bone. Finally, the inner part of the bone is called marrow. There are two types of marrow, yellow and red.
Yellow is made of fat cells and red produces blood cells, some kinds of white blood cells and platelets.
The skeleton of a newborn is composed almost entirely of cartilage. Cartilage is replaced by bone through ossification.
Depending on its type of movement, a joint is classified as immovable, slightly movable and freely movable.

Chapter 35 Notes

The eleven organ systems of the human body work together to maintain homeostasis. These organ systems are:

  • Nervous 
  • Integumentary
  • Respiratory 
  • Digestive 
  • Excretory
  • Skeletal
  • Muscular
  • Circulatory
  • Endocrine
  • Reproductive
  • Lymphatic
Different tissue types work together within organs. The types of tissue are
  1. Muscle - most common in animals, controls the internal movement of materials such as blood. Also controls external movements like typing
  2. Epithelial tissue - closely packed cells that cover the surface of the body and line internal organs such as the heart to prevent blood leakage. Glands are made of this type of tissue
  3. Connective tissue - holds organs in place and binds different parts of the body together. An example would be a tendon
  4. Nervous Tissue - receives messages from the body's external and internal environments, analyzes data and directs the response. 
Biological systems achieve homeostasis through feedback inhibition. 

The nervous system controls and coordinates functions throughout the body and responds to internal and external stimuli. 

The messages carried by the nervous system are electrical signals called impulses. The cells that transmit these impulses are called neurons. There are three types, motor, sensory and Inter neurons. 

A nerve impulse begins when a neuron is stimulated by another neuron or by its environment. 

There are five general categories of sensory receptors; pain receptors, thermo receptors, mechanorecpetors, chemoreceptros and photoreceptros.

Chapter 34 Animal Behavior Notes

Biologists define behavior as the way an organism reacts to changes in its internal condition or external environment. Behaviors are preformed when an animal reacts to a stimulus. Stimuli is any kind of signal that carries information and can be detected. An internal stimulus could be stomach pain when you are hungry. An external stimulus could be your phone ringing. A single specific reaction to a stimulus such as waking up when you hear an alarm is called a response.
Animals can detect many types of stimuli such as light, sound, odors and heat. Not every animal can detect every kind of stimuli and some can detect interesting or odd stimuli such as the earth's magnetic field.
When an animal responds to a stimulus, body systems including the sense organs, nervous system and muscles interact to produce the resultant behavior. Innate behaviors appear in fully functional form the first time they are performed, even though the animal may have had no previous experience with the stimuli to which it responds.
The four major types of learning are habituation, classical conditioning, operant conditioning and insight learning.
