Answer:
The correct answer will be option C- endothelial cells of the endocardium.
Explanation:
The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.
This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.
Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.
Answer:
Appropriate Question:-
The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.
Given:-
Mass of woman=m=60kg.
Height=h=3m
Time=t=3.5secs.
To find :-
Here we want to calculate the output for a woman
Here first we should calculate work done first.
work \: done = mghworkdone=mgh
Applying the values,
work \: done = 10 \times 60 \times 3workdone=10×60×3
Work done= 1800Joule.
Now , lets calculate power,
power = \frac{workdone}{time \: taken} power=
timetaken
workdone
Now,
Applying the values ,
power = \frac{1800}{3.5} power=
3.5
1800
Power =514.2857 watt.
Hope it helps u mate .
Thank you .
Answer:
The correct answer is option B- pressure within the alveoli.
Explanation:
Intrapulmonary pressure is the pressure within the lungs especially in the alveoli of the lungs so is also known as "intra-alveolar pressure".
This pressure helps in the breathing process as :
1. During inspiration - The thoracic cavity volume increases due to which the intra-pulmonary pressure becomes less than the atmospheric pressure which causes the lungs to inhale about 500 ml of air.
2. During expiration- the thoracic volume decreases which cause the intra-pulmonary pressure larger than atmospheric pressure which causes the lungs to exhale the air.
Thus, option B- pressure within the alveoli is the correct answer.
Answer:
Intramembranous ossification:
Intramembranous ossification, the development of osseous tissue occurs without the cartliage formation. The bone forms on the mesenchyme tissue. No intermediate cartilage is formed in this type of ossification. This process is important for the formation of flat bones.
Endochondral ossification:
Endochondral ossification, the development occurs from the center and true bone tissue is replaced in this type of ossification. The cartilage formation occur in this process. An intermediate cartilage is formed in this type of ossification. This process is important for the formation of long bones.
Removal of mole on the abdomen primary prevention strategy does the nurse recommend to a client concerned about development of cancer.
Cancer occurs when a few of the body's cells grow out of control and spread to other internal organs. The trillions of cells that make up the human body are home to cancer, which can develop practically anywhere. Cancers are any of the many diseases that are characterized by the expansion of abnormal cells that divide uncontrollably, have the ability to penetrate, and cause harm to good physiological tissue.
Cancer cells acquire gene alterations that transform them from healthy cells to cancer cells. These gene mutations can be passed down via families, develop gradually as we age and our genes deteriorate, or show up if we are exposed to chemicals that damage our genes, such as alcohol, tobacco smoke, or ultraviolet (UV) radiation from the sun.
