Unlike endocrine glands, exocrine gland RELEASE SECRETIONS OUTSIDE OF THE BODY.
There are two types of glands in the body, the endocrine and the exocrine glands. The endocrine glands are ductless glands and their secretions are normally released directly into the blood stream. The exocrine glands on the other hand have ducts, through which their secretions are release outside the body. An example of this is the sweat gland.
The nurse will explain to the client is
the catheterization will visualize the disease process in the coronary arteries.
A cardiac catheterization delivers information on how well a heart
works, recognizes problems and allows for procedures to open blocked
arteries.
For example, during cardiac catheterization your doctor may:
<span>
Gather
up samples of blood to measure the oxygen content in the four chambers of
your heart.
<span>Take X-rays using
contrast dye injected over the catheter to look for narrowed or blocked
coronary arteries. This is known as coronary arteriography or coronary
angiography.
</span>
Assess
the ability of the pumping chambers to contract.
Look
for deficiencies in the valves or chambers of your heart.
Execute
a percutaneous coronary intervention (PCI) such as coronary
angioplasty with stenting to open up narrowed or blocked segments of
a coronary artery.
Check
the compression in the four chambers of your heart.
Remove
a small piece of heart tissue to examine under a microscope (biopsy).</span>
Answer:
The presence of organelle DNA in mitochondria and chloroplast supports the theory that mitochondria and chloroplast originated as independent prokaryotic organism.
Explanation:
- The more well documented and generally accepted theory for the origin of eukaryotic organelles is Endosymbiotic Theory. (Margulis 1970).
- Recent evidences justify that organelles have originated from the endosymbiotic association of ingested aerobic and and photosynthetic prokaryote, the precursors of mitochondria and chloroplast respectively.
- Molecular data have played an important role in supporting the xenogenous origin rather than autogenous origin of organelles.
- The idea of independent existence of mitochondria and chloroplast are: they are replicators; they carry genetic information; they have protein synthesising machinery; they have ribosome of prokaryotic type.
- The prokaryotic or bacterial origin of mitochondria and chloroplast is supported by the fact like their DNA is simple ,closed and circular with single point of origin; DNA controls the synthesis of their rRNA and tRNA etc.; They have their own ribosome; antibiotic specificity.
The reason animals need a continuous supply of oxygen is to<u> Obtain energy from their food.</u>
<u></u>
The most fundamental reason why animals need a non-stop delivery of oxygen is without it animals can't achieve sufficient power from their meals.
Cells require a steady delivery of power to generate and preserve the biological order that keeps them alive. This electricity is derived from the chemical bond energy in food molecules, which thereby function as fuel for cells.
The animal's metabolism converts oxygen into strength. All through this system, a waste gas called carbon dioxide is produced. To remove it, the carbon dioxide is carried lower back to the lungs, where its miles are collected and exhaled.

Answer:
Vagus nerve
Explanation:
Vagus nerve is the tenth cranial nerve that can innervate in the neck, thorax and abdomen.
Thyroid gland is located below the neck region and releases thyroxine hormone. Vagus nerve innervates in the thyroid gland. Parasympathetic fibres of thyroid gland comes from the vagus nerve and symapthetic fibres is distributed in the superior, middle and inferior ganglia of sympathetic trunk of the thyroid gland.
Thus, vagus innervates in the thyroid gland.
