Anatomy Review - Quiz 2 and later Flashcards
Right-sided HF
- symptoms
- causes
- back up of blood in the lung (because of left-sided HF) is too much for the RV
- dilation of the RV, RA, and SVC (cardiomegaly), edema in lower extremities
What is anemia? What is it caused by? How does it appear on x-ray?
- Abnormally low levels of RBCs in the blood
- caused by low iron, chronic blood loss, or malignant tumor
- patients appear pale, fatigue, shortness of breath, increased heart rate and respiration
- appears as osteoporosis in bones, medullary canals wider
Branches of Aorta (from left to right)
- Left Subclavian Artery
- Left Common Carotid Artery
- Brachiocephalic Trunk
Addison’s Disease and side effects
Insufficient production of cortisone
- hyperglycemia, weight loss, fatigue
- enlargment of adrenal glands visualized by MRI and CT
What is an embolus?
-clot (fat, air, plaque, amniotic fluid) moving through the blood stream
What is a thrombus?
-a clot on the inside lumen of the vessel (attached to wall)
Describe specific humoral/adaptive immunity
- run by B-cells
- plasma cells: antibodies
- memory cells: remember the pathogen
Heart Failure types
- Left-sided HF (congestive heart failure)
- Right-sided HF
Cushings Syndrome
- excess levels of glucocorticoids in the blood stream caused by pituitary/adrenal gland pathologies, but mostly from treatment of inflammation with antiinflammatories
- obese trunk of body, buffalo hump, moon face, loss of bone densifty and muscle mass
Myocardial Infarction and its symptoms
- death of heart muscle from blockage in the coronary arteries (heart attack)
- chest pain
- shortness of breath
- numbness/tingling in left arm
- sweating profusely
- pale
Diabetes Mellitus and its types
- high blood sugar levels
- Type 1: jeuvenile, body doesn’t produce insulin
- Type 2: adults, body doesn’t recognize insulin anymore
- increase thirst, increased urine production, infection, gangrene from decreased circulation (sticky blood)
What hormone(s) does the pituitary gland produce?
Posterior: stores ADH which stops production of urine
Anterior:
-TSH: thyroid stimulating hormone
-GH: growth hormone
-ACTH: adrenocorticotropic hormone (stimulates adrenal glands)
Pulmonary edema
- build up of fluid in the interstitial spaces if the lung parenchyma due to increase pulmonary venous pressure
- caused by left-sided heart failure, but may originate from valve disease, left-atrial tumor, or lymphatic blockage
- “drowning from the inside out”
Types of aneurysms
- (Saccular)/Berry: bulge on one side of vessel
- Fusiform: bulge on both sides of vessel
- Dissecting: blood in walls of vessel
Atherosclerosis
-most commonly in what vessels?
- hardening of the arteries due to “porridge”-build up of plaque, build up of WBCs and platelets, or a thrombus
- most commonly in abdominal aorta, common iliacs, femoral, cerebral, coronary arteries
Describe cell mediated immunity
- run by T-cells
- if they get overrun they send a “help” signal to the B-cells
The important types of WBCs:
-lymphocytes
-monocytes
Both are non-granular
What are the layers of the heart?
- Pericardial Sac (parietal pericardium)
- Epicardium (visceral pericardium)
- Myocardium
- Endocardium
Atrial septal defect (patent foramen ovale)
- hole between the right atrium and left atrium fails to close off
- blood from the left atrium flows to the right atrium and through the circuit again
- enlargement of affected vessels/parts
- increased lung markings
Ventricular septal defect
- abnormal opening between the right and left ventricles
- blood flows from the left ventricle to the right ventricle
- enlargement of left ventricle, left atrium, and pulmonary trunk, increased lung markings
Difference between myelocytic and lymphocytic leukemia
- Myelocytic: causes increase in WBCs in bone marrow, radiolucent bands in metaphyses
- Lymphocytic: causes increase in WBCs in lymphatic, swollen gland and lymphnodes, enlarged spleen
Arrythmia
-types
- any condition where the heart cannot beat normally
- bradycardia: slow heart rhythm
- tachycardia: rapid heart rhythm
- premature contractions: heart contractions that occur before the expected time
- fibrillation: individual cardiac muscle contractions are out of sync
What hormone does the parathyroid glands secrete?
Parathyroid hormone: increases blood calcium levels by stimulating osteoclasts to break down bone
What does hyperpituitarism cause?
Giantism: in children
Acromegaly: in adults
What does the thyroid gland secrete?
- Thyroid hormone: speeds up metabolic processes
- Calcitonin: decreases blood calcium levels
Diabetes Insipidus and side effects
Antidiuretic hormone insufficiency caused by trauma to the head
-polyuria and intense thirst
Dwarfism
Underproduction of growth hormone (hypopituitarism)
Short limbs, but body is proportional
Blood composition
- 55% plasma
- 45% formed elements
