What occurs at the 14th day of the female cycle? - ANSWER✔️A surge of LH is released from
the pituitary gland.
What is the function of LH? - ANSWER✔️Stimulate ovulation and the conversion of the corpus
to the corpus luteum.
What does the corpus luteum secrete? - ANSWER✔️Progesterone and estrogen which stimulates
the development of the endometrium.
What happens if fertilization occurs? - ANSWER✔️The corpus Luteum remains functional.
What occurs when fertilization does not occur? - ANSWER✔️The corpus luteum degenerates and
menstruation begins.
What occurs to the egg after ovulation? - ANSWER✔️The egg is swept to the oviduct or
fallopian tube.
What occurs to the fertilized egg? - ANSWER✔️The zygote travels to the uterus and is implanted
to the endometrium.
What nourishes the fetus in the uterus? - ANSWER✔️The embryo is nourished by the placenta.
,What forms the placenta? - ANSWER✔️Maternal and embryonic tissue.
What are the two major portions of the pituitary gland? - ANSWER✔️Anterior lobe-
adenohypophysis
Posterior lobe-neurohypophysis

45% formed elements: erythrocytes, leukocytes, platelets.
Where are all the elements in blood formed? - ANSWER✔️Red bone marrow.
What are erythrocytes transformed for? - ANSWER✔️The transport of O2.
What is most O2 bound to in erythrocytes? - ANSWER✔️The pigmented protein hemoglobin.
, How are the five types of leukocytes distinguished? - ANSWER✔️Size
Appearance of nucleus

What is the function of blood? - ANSWER✔️O2 transport
Carry CO2 and metabolic waste away
What is found in 10% of plasma? - ANSWER✔️Proteins
Ions
Nutrients
Waste products
Hormones
All these dissolve or suspend in H2O.
What is the function of the heart? - ANSWER✔️Sends blood to lungs for oxygenation through
the pulmonary circuit & to the remainder of the body through the systemic circuit.
Where is blood received in the heart? - ANSWER✔️Blood is received in the atria
Where is blood pumped into circulation in the heart? - ANSWER✔️The ventricles
Which valve is on the right side of the heart? - ANSWER✔️Tricuspid
Which valve is on the left side of the heart? - ANSWER✔️Bicuspid
Where are the semilunar valves in the heart? - ANSWER✔️Found at the entrances of the
pulmonary trunk and the aorta.
What supplies blood to the myocardium? - ANSWER✔️The coronary arteries
Where does blood drain to from the myocardium? - ANSWER✔️Directly into the right atrium
through the coronary sinus.
Where is the heart beat initiated? - ANSWER✔️By the sinoatrial node and transmitted along a
conduction system through the myocardium
