What is the muscle to aid breathing in a fetal pig?

Diaphragm
Diaphragm. This muscle divides the thoracic and abdominal cavity and is located near the ribcage. The diaphragm aids in breathing.

What is the function of the pulmonary trunk in a fetal pig?

Pulmonary Trunk — This artery leaves the heart on the ventral surface from the right ventricle and angles to the left. 8. Pulmonary arteries — The main pulmonary trunk divides into these vessels. In the adult, the pulmonary arteries carry deoxygenated blood to the lungs.

What structures in the fetal pig allow circulation to bypass the lungs?

The shunt that bypasses the lungs is called the foramen ovale. This shunt moves blood from the right atrium of the heart to the left atrium.

What is the function of the umbilical arteries in a fetal pig?

umbilical arteries: two arteries, carry deoxygenated blood from fetus to placenta.

What portion of the brain controls voluntary muscle movements fetal pig?

Behind the olfactory lobes is the cerebrum. The cerebrum is divided into two cerebral hemispheres by a deep groove named the longitudinal cerebral fissure. The cerebrum of most mammals has a folded surface. The cerebrum controls voluntary muscle movements, thinking, memory, judgment, and the senses.

What is the tissue that covers and protects the lungs?

pleura. A thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity. It protects and cushions the lungs. This tissue secretes a small amount of fluid that acts as a lubricant, allowing the lungs to move smoothly in the chest cavity while breathing.

What is the function of the heart in a pig?

Pigs like other mammals have a four-chambered heart. The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation).

What is the largest vein in a fetal pig and why?

The largest vein in the body is the vena cava which brings deoxygenated blood from the body back to the heart and lungs to be reoxygenated.

What is the function of the bladder in a fetal pig?

The renal pelvis of each kidney drains into a coiled tube called the ureter. The ureters lead from the kidney to the urinary bladder, where urine is temporarily stored.

What part of the human body is in control of all voluntary movement?

cerebrum
The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.

What portion of the brain controls voluntary muscle movements?

The biggest part of the brain is the cerebrum. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to.

What keeps mucus and dirt out of the lungs?

On the way down the windpipe, tiny hairs called cilia (say: SILL-ee-uh) move gently to keep mucus and dirt out of the lungs.
