    (1) primary bronchi
    (2) pulmonary arteries and veins
    (3) bronchial arteries and veins
    (4) lymph vessels and nodes
    (5) nerves
  • Apex of the lung is the point of upper margin which extends slightly above the clavicle
  • base of the Lung is broad inferior surface which lies on the diaphragm.
  • the left lung has an indentation for the heart called the cardiac notch or depression

21
Q

The lungs contain the alveoli which are essential for gaseous exchange

  1. ….
  2. ….
A
  1. Thin walled sacs are enveloped by a network of capillaries
  2. As blood circulates through the capillaries, CO2 diffuses through the cell membrane and is exchange w oxygen
22
Q

Lobes of the lung

A

A. Left Lung

(2) left lower lobe

B. Right Lung

(1) Right Upper Lobe
(2) right middle lobe
(3) right lower lobe

23
Q

Functions of the lung

A

A. Acts is essential organ for respirations by distributing out of the lungs into the alveoli

B. Furnish a place where air can come in close enough contact with blood for gaseous exchange to occur

C. Acts as an excretory organ because an individual loses about 400 cc. of moisture per day in expired air

24
Q

Characteristics if pleura

A
  1. Parietal pleura is a serous membrane which contains the line and lines the thoratic cavity, each side has it’s own pleura lining
  2. Visceral pleura covers the outer surface of each lung
  3. Pleura space is the potential space formed by the visceral and parietal pleura lying adjacent to each other which contains pleura fluid
  4. Pleura fluid is secreted by the serous membrane to act as a lubricant
  5. Excess secretion of pleura fluid results in pleura effusion
25
Q

A. Pleural Cavities (2)- Area occupied by the lung
B. Mediastinum- space between the lungs
C. Pericardium- area occupied by the heart

26
Q

Diaphragm

A
  1. Some shaped muscle
  2. Primary muscle involved in breathing
  3. On inspiration, it contracts, flattens, and moves downward to enlarge the thoratic cavity
  4. On expiration, it relaxes, moving upward to decrease the size of the thoratic cavity
  5. Has 3 hiatuses or opening for
    A. Esophagus
    B. Aorta
    C. Inferior Vena Cava

  1. Exterior intercostals elevate the ribs
  2. Internal intercostals depress the ribs
27
