Answer 1

Answer:

c is the right answer I think

Answer 2

Diaphragm present in mammals is (c) partition between the thoracic & abdominal cavities

What is a Diaphragm?

• It separates your chest cavity from your belly and is located beneath your lungs.
• Chest pain and breathing difficulties can result from the diaphragm's malfunction, which can be caused by a variety of illnesses, traumas, and ailments.
• The diaphragm's main job is to enable breathing to happen (inhale oxygen, exhale carbon dioxide from the lungs).
• In addition to increased abdominal pressure for feces, urine, and vomit expulsion, secondary functions include applying pressure to the esophagus to avoid acid reflux from the stomach.
• The single organ that only mammals possess and without which no animals can survive is the diaphragm.
• The human is the only mammal whose diaphragm remains parallel to the ground when moving.

Functions of Diaphragm:

• The elastic recoil process of the lung and the tissues lining the thoracic cavity causes air to be expelled as the diaphragm relaxes (moves in the superior direction).
• The internal intercostal muscles are employed in conjunction with the abdominal muscles, which operate as an antagonist paired with the diaphragm's contraction, to assist this function with physical effort (called forced exhale).
• The diaphragm is not always necessary for breathing in non-human animals; a cow, for example, can live with diaphragmatic paralysis relatively symptom-free as long as no significant aerobic metabolic demands are placed on it.
