15. Which type of sensory receptor will detect and respond to changes in blood pressure?

Mechanoreceptor d. None of the Above
Explanation / Answer
1. Release of norepinephrine from nervous system causes increased heart rate and decreased cardiac output by sympathetic Beta1 adrenergic receptor and pupil dilation also called mydrias by alpha 1 adrenergic receptor
2. All tumors are not cancerous. A tumor becomes cancerous when celll becomes malignant.In benign tumors growth is limited to certain body parts. Cancer occurs when cell replication is out of control.
3.Microbes acquired by stepping on a nail will be taken up by immune cells and travel to Lymph node the to initiate an immune response.
4 Metastatic tumors cannot be removed using surgical treatment. State thetype of cancer, not a specific organ.
5. One of the major functions of the skeletal system is Blood Cell Production. In the skeletal system tissue inside log bone like femur contain red bone marrow producing red blood cells.
6.Thyroid gland is part of endocrine gland while sweat gland is part of exocrine gland.
Endocrine glands secrete hormones internally through blood stream . Eg: Adrenal gland( top of kidneys), ovaries, Pitutary gland, Pineal gland (underneath brain) pancreas ( in the abdomen) hypothalamus, Parathyroid ( embedded in the back of thyroid gland)Pineal gland, Testes, thymys( above the heart)
Exocrine glands secrete internally and externally through ducts into organ or surface.Eg: salivary glands in mouth.
8. Blood flowing is pulmonary artery is oxygen poor. Pulmonary artery carry deoxygenated blood from right ventricle of heart to lungs for purification.
9.Genes that induce tumor growth by increasing cell proliferation are known as Oncogenes.
10.Golgi apparatus (or golgi body) is important for Modifying ER molecules &Cellular export of proteins.Golgi apparatus mainly modifies proteins moved from rough ER through cis-golgi network and exits from golgi through trans-golgi network.
The breakdown of molecules donot occur instead simple molecules are packaged into complex molecules for cell secretion.
11.Insulin is a hormone used by cells to store energy (glucose) after a meal.
After a meal the glucose in the blood stimulates beta cells of pancreas to release insulin.
12 Laryngitis is caused by upper respiratory tract virus Parainfluenza, rhino virus, influenza virus and bacteria Streptococcus pneumonia.
Otitis media is inflammation and accumulation of fluid in middle ear caused by virus such as adenovirus, rhinovirus, corona virus. and bacteria Streptococcus,Haempphilus
Pneumonia is caused by lower respiratory tract virus Influenza pneumonia, parainfluenza pneumonia ,respiratory syntitial pneumonia virus and bacteria by Streptococcus pneumonia.
13. Trait of malignant tumors: Life-threatening ,Poorly differentiated ,Spreads to other body parts.
14. Both males and females make progesterone. Progesterone is produced by testis in men and ovaries in female. Progesterone is precursor of hormones estrogen and testosterone.
15. The type of sensory receptor will detect and respond to changes in blood pressure is mechanoreceptor. Baroreceptor, an example of mechanoreceptor mainly detects changes in blood pressure.
