Q
  1. The release of the egg (ovum) from the ovary
  2. The egg is released when the cavity surrounding it (the follicle) breaks open in response to a hormonal signal
  3. It occurs around 14 or 15 days from the first day of the woman’s last menstrual cycle.
    When this occurs the ovum moves into the fallopian tube and becomes available for fertilization

Q

What is the function of a nephron

functional unit of a kidney

A
  1. Its chief function is to–regulate water and soluble substances by filtering the blood, reabsorbing what is needed and excreting the rest as urine
  2. They eliminate wastes from the body
  3. Regulate blood volume and pressure
  4. Controls levels of electrolytes and metabolites
  5. Regulate blood pH
18
Q

The part of a kidney tubule that forms a long loop in the medulla of the kidney, from which water and salts are resorbed into the blood

A

Loop of Henle

19
Q

What is the Function of the Scrotum

A

A sac to hold and support the testis outside the body, allowing sperm to develop at a temperature lower that that of the internal body

20
Q

The numerous areas of lymphoid tissue in the wall of the small intestine that are involved in the development of immunity to antigens present there

A

Peyer’s Patches

21
Q

Function of Hemocytoblast

Type of stem cell in bone marrow

A

Capable of developing into any type of blood cell

22
Q

Function of Cells in Aveoli

A
  1. Forms structures of alveolar walls
  2. Secrete pulmonary surfactant–To lower surface tension of water + allows the membrane to separate, increasing its capability to exchange gases
  3. Destroy foreign material (bacteria)
23
Q

What triggers Antibodies

A

Antigens

Once the immune system detects the presence of antigens, it triggers an antibody response

24
Q

What substances needed for normal RBC

(red blood cell) production

A
  1. Folic acid
  2. Vitamin b12
  3. Needs Intrinsic Factor derived from stomach for absorption, of B12
25
Q

An enzyme that helps digest CHO (carbohydrates)

A

Amylase

26
Q

Enzyme that aids in the breakdown of triglycerides

A

Lipase

27
Q

Why do we need dietary fats

A 
1.  Provides ENERGY needed for growth
and basic body functions
2.  Cushions your organs
3.  Helps body absorb fat-soluble vitamins
4.  Contributes to health of skin
5.  HELPS prevent common cold
28
Q

What ion is found in intracellular flluid

liquid contained inside the cell membranes

A

Potassium

29
Q

What ions control water volume

A

Sodium Ions

30
Q

What influences the change of K (potassium)

A
  1. Blood Glucose Levels
  2. Adrenal Function
  3. Changes in Na+ Levels (Sodium)
  4. pH Changes
31
Q

What is Cerebral Circulation

A

The supply of BLOOD TO BRAIN

32
Q

What is Coronary Circulation

A

The blood supply to the CARDIAC MUSCLE

33
Q

What is the function of the Glomerular Capsule (also called Bowman’s Capsule)

(thin membrane that surround glomerulus of a nephron)

A
  1. Performs 1st Step in FILTRATION of Blood to Form Urnie
  2. It allows liquids + small particles of solids to pass through but prevents larger structures (blood cells) from passing through
34
Q

What is Pulmonary Circulation

A

Circulation of blood between HEART + LUNGS

35
Q

What is Hepatic Portal Circulation

A
  1. System of Veins made up of the Hepatic Portal VEIN and its tributaries
  2. The return of venous blood from the digestive organs and spleen through a capillary network within the liver before draining to the heart
36
Q

Interstitial Cells

A
  1. The cells of the connective tissue of the ovary or the testis, which furnish the internal secretion of those structures
  2. Also called Leydig Cells
37
Q

A vein carrying OXYGENATED blood from the lungs to the LEFT ATRIUM of the heart

A

Pulmonary Veins

38
Q

What is needed by body to absorb Intrinsic Factor

A

Vitamin B12

39
Q

Where and How does Blood Cell Formation take place

A

WHERE-Red Bone Marrow

HOW-Erythropoietin, a hormone produced mostly by the kidneys, stimulates bone marrow to produce erythrocytes

40
Q

Inadequate blood supply to a local area due to blockage of blood vessels leading to that area

A

Ischemia
