Adrenal gland
Organ under the stomach
Pancreas
Where is the thymus located?
above the heart
Describe the Gonads
In reproductive system
Function of the pituitary gland
stimulate growth and secrete hormones such as ADH
Function of the thyroid gland
increase metabolism and lower plasma calcium levels
Function of the parathyroid gland
increase calcium plasma levels
Function of the adrenal gland
Cortex- regulate metabolism, and
Medulla- enhance “fight or flight response
Function of the pancreas
control blood glucose
Function of thymus
maturation of T lymphocytes
Function of gonads
maintain reproductive organs
The endocrine system is the control system connected to the nervous system by the
hypothalamus
What are the functions of blood?
Transporation and protection
Function of Albumins
Plasma that give osmotic grad.
Function of Globulins
Plasma-
Alpha-transport
Beta-transport
Gamma-produce antibodies
Function of Fibrinogen
Plasma-
Blood clot
Name the five type of leukocytes
- Neutrophils
- Eosinophils
- Basophils
- Lymphocytes
- Monocytes
Name the granulocyte leukocytes
Neutrophils, Eosinophils, Basophils
Name the agranulocyte leukocytes
Lymphocytes, monocytes
Function of Neutrophils
carry on phagocytosis, 1st on site
Function of Eosinophils
Invade parasites and for allergic reactions
Function of Basophils
Make histamine and heparin
Function of Lymphocytes
become T and B-cells
Function of Monocytes
Carry on phagocytosis (macrophages)- diapedesis
What is hemopoiesis?
Blood production
`Describe the path of the pulmonary circuit.
Right side pumps to lungs and back to heart (deoxygenated blood)
Describe the path of the systematic circuit.
Left side pumps with reoxygenated blood going to the body
What part of the heart contains the thickest myocardium?
Left Ventricle
Name the 5 auto rhythmic tissues found in the heart
- Sinoatrial (SA) node
- Atrioventricular (AV) node
- Atrioventricular bundle
- Bundle branches
- Purkinje fibers
Location and rapid of fire of the SA node
at top of right atrium, 70-80 x/min.
Location and rapid of fire of the AV node
at center corner of right atrium, inferior interatrial septum of the right atrium, 40-60 x/min
Location and rapid of fire of the Atrioventricular bundle (Bundle of His)
top of the interventricular septum, 15-40 x/min
Location and rapid of fire of the bundle branches
on either side of interventricular, 15-40 x/min
Location and rapid of fire of the purkinje fibers
branch out in right and left ventricles, 15-40 x/min
What valve is found between the right atrium and right ventricle?
Tricuspid Valve
Name the stretchy strings which anchor the bicuspid and tricuspid valves.
Chordae Tendineae
Define Fibrin
The formation of a blood clot
Name the depression found in the interatrial wall of the right atrium
Fossa Ovalis
What is the purpose of the semilunar valves?
Prevent backflow of blood into ventricles
What is the vasa vasorum?
The circulatory system within blood vessel walls
What is the lumen?
The empty space in the blood vessel for blood flow
What is aneurysm and what could it lead to?
Weakening in the vessel wall-could rupture
