Human Phisiology Flashcards
Cover body services and line organs
Epithelial tissue
Binds and supports other tissues
Connective tissue
Tissue under skin
Loose connective tissue
Fat tissue
Adipose tissue
Tendon and ligament tissue
Fibrous connective tissue
The tissue found in the bones
Bone tissue
Cells in extracellular matrix
Blood tissue
Other two types of body tissue
Nerve and muscle tissue
System that processes food
Digestive system
System that deals with gas exchange
Respiratory system
System transports nutrients wastes
Circulatory system
System that deals with protection
Immune system
System that deals with the coordination of body functions
Endocrine system
System that deals with the detection and response to stmuli
Nervous system
System that deals with structure, support and blood cell production
Skeletal system
System that deals with movement and protection
Muscular system
System that deals with carrying on genetic code to the next generation
Reproductive system
System that deals with protection and keep the body from drying out
Integumentary system
The four steps of the digestive system is to____?
Ingest
Digest
Absorb
Eliminate
The organs included in the digestive system are_____?
Mouth Esophagus Stomach Small intestine Large intestine Rectum Anus
Type of digestion that takes place with the teeth, peristalsis in stomach, and the intestine
Mechanical digestion
Type of digestion that has acids and enzymes convert food into Acid chime which is released into small intestine
Chemical digestion
Made up of hydrogen chloride, mucus, and inactive pepsin called pepsinogen which digests proteins; hydrogen chloride converts inactive pepsinogen into active pepsin and the mucus protects the lining of the stomach.
Gastric juice
First 20 to 25 cm duodenum where nutrient absorption and most chemical digestion take place
Small intestine
Secretes digestive enzymes and alkaline solution to neutralize acid chime
Pancreas
Secretes bile, stored in gallbladder, breaks down fats
Liver
Projections in intestine, highly vascularized, helps absorb nutrients into blood
Villi and microvillous
Consolidates waste, removes water, bacteria synthesize vitamin K
Large intestine
Organic nutrients that are obtained through diet; important as coenzymes
Vitamins
Inorganic nutrients we obtain from diet; usually only needed small amounts; essential in some enzymes, for proper cell function, and as a component or precursor for many compounds
Minerals
The main component of the human respiratory system
Lungs
Order organs used in the respiratory system
Nose/mouth Larynx Trachea Bronchi Bronchioles Alveoli
Contraction of this allows for air movement
Diaphragm
The diaphragm contracts and moves down during
Inhalation
The diaphragm relaxes and moves up during
Exhalation
What parts in the brain help control breathing
The pons and medulla oblongata
What other things in the body help control breathing
pH levels in the blood
Whenever excess oxygen detected in carotid and aorta stops sending nerve impulse to rib muscles and diaphragm.
Hyperventilation
Do humans have open or closed circulatory system
Closed
Carry blood away from the heart
Arteries
Carry blood towards the heart
Veins
Region of nutrients/waste exchange with the cells
Capillaries
Small branches of arteries that lead to capillaries
Arterioles
Small veins that converge to form veins
Venules
Humans have what kind of circuit
Double circuit
The circuit dealing with the heart and lungs
Pulmonary circuit
The circuit dealing with the heart and the remainder of the body
Systemic circuit
What’s the order of the parts of the body that the blood goes to
Body Superior and inferior Vena cava Right atrium Right ventricle Pulmonary artery Lungs Pulmonary vein Left atrium Left ventricle Aorta Body
Type of heart problem that causes myocardial infraction; heart attack, blood flow to the heart muscle is interrupted
MI
Type of heart problem with plaque buildup in coronary arteries
Atherosclerosis
What causes atherosclerosis
It can be genetic Diet Smoking Stress Being inactive
Globular protein in blood of most vertebrates, contains iron, binds and carries carbon dioxide and oxygen
Hemoglobin
CO2 is converted into what in the blood
Bicarbonate ion
How many oxygen molecules can one hemoglobin molecule carry
Four
What does the blood do
Carries nutrients, waste, cells
Regulates the body temperature
Stabilizes pH
Part of the heart that receives blood not as muscular
Top atria
Part of the heart that pumps blood, very muscular
Bottom ventricle
Does the right side of high or low oxygen content
Low
Does the left side of the heart have high or low oxygen content
High
Condition of heart whenever it is relaxed and blood flows into all chambers
Diastole
Condition of the heart whenever It pumps and begins filling atria.
Systole
Type of pacemaker found in the upper portion of the right atrium
Sinoatrial node
Type of pacemaker found in the wall between right atrium and right ventricle
Atrioventricular node
What hormone determines the rate of the heart
Epinephrine
What makes up 55% of the blood
Plasma
What is plasma Made of
Mostly H2O
Minerals
Nutrients
Red blood cells are this type of cell
Erythrocytes
White blood cells of this type of cell
Leukocytes
Histamine producers
Basophils
Combat parasites
Eosinophils
Most numerous, phagocyteic
Neutrophils
T cells and B cells
Lymphocytes
Lead to macrophage, phagocytic
Monocytes
Aid in clotting of blood
Platelets
Cells found in long bones red bone marrow and spleen; the cells have not differentiated into what particular cell they will be; potential for variety of medical treatments
Stem cell
Part of the immune system that’s nonspecific; it’s the first line of protection
Innate immunity
Neutrophils, monocytes and macrophage
Phagocyte cells
Cells that fight cancer and viruses
Natural killer cells
Proteins produced by cells to fight a virus
Interferons
Blood proteins that work like a domino effect where one protein binds and activates another
Complement
Any foreign material that can stimulate immune response
Antigen
Protein produced by B cells that specifically recognize a particular antigen and aid in immune response have Fc regions that attach to cells and antigen binding regions that specifically attach to antigen
Anti-body
