The autonomic nervous system and hormones released by the adrenal medulla contribute to the regulation of heart rate and contractility. Acetylcholine will (increase/decrease) heart rate as it is the neurotransmitter released by the (sympathetic/parasympathetic) nervous system at the SA and AV nodes.
Decrease; Parasympathetic
Epinephrine will ________ heat rate and strength of contraction. Epinephrine is a hormone released by the adrenal medulla which is considered to be part of the __________ nervous system.
Increase; Sympathetic
Transfusion rule:
Recipient’s antibodies must not match donor’s antigens
Allows the oxygen-rich blood to bypass the liver
Ductus venous
Brings oxygen rich blood to the fetus in the umbilical cord
Umbilical vein
Allows blood to bypass the lungs once it enters the right atrium
Foramen Ovale
Branches off the fetal internal iliac arteries to return wastes and CO2 to the placenta
Umbilical arteries
Allows blood to bypass the fetal lungs once blood has entered the pulmonary trunk
Ductus arteriosus
ECG - Artial depolarization
P Wave
ECG - Ventricular depolarization
QRS Complex
ECG - Ventricular repolarization
T Wave
The fetus is supplied with oxygen and nutrients via __________ _____ in the umbilical cord
Umbilical vein
(Fetus) Umbilical vein in the umbilical cord carries blood from the ________ to the fetus
Placenta
(Fetus) The _________ ________ allows most of the blood to bypass the fetal liver and enter directly into the inferior vena cava
Ductus venosus
(Fetus) The ductus venosus allows most of the blood to bypass the fetal liver and enter directly into the ____________________
Inferior vena cava
(Fetus) The ___________ _______ and foramen ovale allow the blood to bypass the nonfunctional fetal lungs
Ductus arteriosus
(Fetus) The ductus arteriosus and _________ _____ allow the blood to bypass the nonfunctional fetal lungs
Foramen ovale
(Fetus) Metabolic wastes and carbon dioxide are moved from the fetus in blood carried by ____________ ________, which are branches of the fetal internal iliac arteries
Umbilical arteries
(Fetus) Only the ___________ ______ contains oxygenated blood, as all other fetal vessels carry a mixture of oxygenated and deoxygenated blood
Umbilical vein
During the process of accommodation for close vision, the lens of the eye becomes (more round/flatter) because the ciliary muscle (contracts/relaxes) (increasing/decreasing) the tension of suspensory ligaments
More round; contracts; decreasing
The area of the retina responsible for the greatest visual acuity is the
Fovea centralis
Eosinophils range from _ to _ % of the total WBC population
2; 4
A total white blood cell count in a heathy individual would be
5,000-10,000 cells/mm3
The leukocyte that produces antibodies is the
Lymphocyte
Embryonic mesoderm gives rise to:
Muscle, blood, bones, heart, kidneys
Membranous structures of the inner ear involved in static equilibrium are the
Saccule, utricle
Name 3 accessory glands in the male that contribute to secretions to form seminal fluid:
Prostate gland, seminal vesicle, bulburethral gland
Absorbs water and form feces:
Large intestine
Food passageway posterior to trachea
Esophagus
Secretions from this structure initiate protein digestion
Stomach
Membrane joining the lesser curvature of the stomach to the liver
Lesser omentum
Finger-like extensions of the intestinal mucosa that increase the surface area for absorption
Villus
Mobile organ that manipulates food in the mouth and initiates swallowing
Tongue
Bone supported roof of the mouth
Hard palate
An ECG recording detects ________ ______ of the cardiac muscle - waves of depolarization/repolarization of atria and ventricles
Electrical activity
Implantation of blastocyst in the uterus at 6 days post fertilization:
Blastocytes adheres to endometrium of uterus. Trophoblast cells - 2 layers - inner layer is cellular trophoblast and outer layer forms _________ __________
Syncytial trophoblast
These cells secrete enzymes & blastocyst is burried in endometrium
Syncytial trophoblast
