Animal Physiology
Nutrition
Nutrient Digestion
Vili are the small hairlike projections in the folds of the small intestine, and absorb nutrients into the bloodstream
Hepatic portal vein leads directly the liver, allows for distribution of nutrients and detoxification of the body
Duodenum is the first 10 inches of the small intestine, and is where all the digestive juices mix
-
Human Digestive Tract
Small Intestine breaks down proteins, carbs, and nucleic acids with chemicals like trypsin and pancreatic amylase. Also the Majority of nutrient absorption happens here
-
Oral Cavity The tongue, teeth, and esophagus aid mechanical breakdown of food , and also a chemical breakdown of carbs via salivary amylase
Large Intestine does mechanical digestion, and reabsorbtion of water
-
Liver Creates bile, which breaks down lipids
Pancreas produces lipase, amylase, trypsin, and nuclease, and so essentialy is necessary for almost all parts of digestion
Nutitional Differences
-
Omnivores regularly eat both plants and meat and need a combination of carbohydrates and proteins, among other things

Form and Function

Tissue Types
Connective Tissue
Fibrous connective tissue is found in ligaments, which connect bones at joints, and tendons, which connect bones to muscle
Cartilage is the strong but flexible support material found in disks between vertebrae, and material in embryo that becomes bone
Adipose tissue insulates and provides energy storage, each cell contains a fat droplet that shrinks or grows depending on energy consumption
Blood contains dissolved proteins, electrolytes, immune defense, oxygen, and mechanisms for clotting
Loose connective tissue Most common tissue vertebrae bodies, holds organs in place, found in skin and throughout the body
Bone is mineralized connective tissue. Osteoplasts release collagen, which later combines with Ca, Ma and P to form osteons
Muscle Tissue
Smooth muscle Involuntary movement, found organs like the stomach and bladder
Cardiac muscle Found in the heart, and is a special type of muscles possessing properties found in both smooth and skeletal muscle
Skeletal muscle Voluntary movement, attached to skeleton//Statified
Nervous Tissue contain neurons and glial cells, with the main concentration of this tissue found in the brain//many lines and connections between cells, and smaller than all others
Epithelial Tissue
-
Stratified Squamous cells regenerate rapidly. Think skin // new cells all jumbled together under old worn out cells
-
-
Cuboidal cells are good for secretion, found in kidneys// individual cells are cube shaped, but form tubules
-
Organ Systems
Immune and Lymphatic Systems like lymph nodes, bone marrow, and the spleen fight off infections and cancer
Excretory Kidneys, bladder, and the urethra allow for removal of metabolic wastes
-
-
Circulatory Heart, blood vessels, and blood all work to exchange material from the environment to inside the body
Nervous Brain, spinal cord, nerves, and sensory organs detect and respond to stimuli
Digestive Organs such as the stomach, pancreas, and esophagus help with food processing
Integumentary Skin and it's derivatives protect against mechanical injuries, infection, and dehydration
Skeletal Bones, tendons, and ligaments provide body support, and protection of internal organs
-
Endocrine The pituitary, thyroid, and adrenal glands allow for coordination of different advanced body activities
