Lecture- Blood,heart, blood Vessels & Lymphatic & respiratory Flashcards
What is blood and its function?
A fluid connective tissue distributing nutrients, oxygen, and hormones to the cells in the body.
Blood consists of what 2 components?
Plasma
Formed elements
Plasma is what?
The liquid component of blood that contains dissolved proteins, nutrients, electrolytes, and wastes
What are the components of formed elements?
Blood cells- red blood cells and white blood cells and cell fragments (platelets)
Function of red blood cells
Transport oxygen and carbon dioxide
Function of white blood cells
Components of the immune system
What are platelets?
Small membrane enclosed packets of cytoplasm containing enzymes and clotting factors
What are the terms for blood volume?
Hypovolenic-low
Normovolemic-normal
Hypervolemic- excessive blood volume
8 functions of blood
- Transport dissolved gases
- Distribute nutrients absorbed in digestive tract
- Transport metabolic waste
- Deliver enzymes and hormones to specific target tissues
- Stabilize the pH and electrolyte composition of interstitial fluids throughout the body
- Prevent fluid losses thru damaged vessels or other injury sites
- Defend against toxins and pathogens
- Stabilize body temp by absorbing and redistributing heat
Mnemonic for white blood cell populations
Never Let Monkeys Eat Bananas
Neutrophils Lymphocytes Monocytes Eosinophils Basophils
Which vessels follow the branching of and run parallel to bronchi and bronchioles?
Pulmonary arteries
Respiratory epithelium is
Pseudostratified ciliated columnar epithelium
The most distal respiratory passage that does not deal with gas exchange
Terminal bronchioles
Main site of gas exchange with capillaries in the lungs
Aveoli
Passageway for inspired air; contains pharyngeal tonsils and opening for auditory tube
Nasopharynx
Small cartilages to which the vocal folds and ligaments attach
Arytenoid cartilage
These cells have an immune function in the removal of pathogens alveoli
Alveolar macrophages
How are bronchioles distinguished from other airways?
They lack cartilage supports and are lined with ciliated simple columnar epithelium
The most inferior surface of the heart is?
Diaphragmatic surface
Phagocytic cell with multi-loved nucleus
Neutrophil
Cell with no nucleus
Mature red blood cell
Darkly staining cytoplasmic granules that release histamine
Basophils
Acidic staining granules with bilobed nucleus and are attracted to antigens
Eosinophils
