Autonomic centers that control blood pressure heart rate and digestion are located in the?
medulla oblongata
What is the main job of the lower part of the brainstem?
The lower portion of the Brain Stem is called the Medulla Oblongata. Its job is to control Cardiac and Respiratory Centers and deals with autonomic and involuntary functions such as breathing, heart rate, and blood pressure.
What is a haemal system?
Blood lacks respiratory pigment.
What part of the respiratory system does blood get oxygen from?
Lungs
What are the three control centers in the Medulla?
Medulla (Oblongata)(part of the brain stem) contains an autonomic reflex center involved in maintaining homeostasis of important visceral organs. It contains several centers: 1. The cardiac center adjusts force and rate of heart contraction. 2. The vasomotor center regulates blood pressure by acting on smooth muscle in the walls of peripheral arterioles. 3. The respiratory center controls the depth and rhythm of breathing.
When blood pH begins to rise the respiratory control centers in the brain are?
depressed
Where are the vital centers for the control of visceral activities?
The hypothalamus influences the autonomic centers in the brain stem and the spinal cord. In this way it regulates many Visceral activites such as heart rate, blood pressure respiratory rate and motility of digestive tract
Why does tachycardia occur w asthma?
fast breathing rate In asthma or other lung diseases, the ability to expire carbon dioxide decreases, resulting in buildup of carbon dioxide in the blood, resulting in respiratory acidosis (decreased pH in the blood). Acidosis stimulates the respiratory centers in the brain, causing the respiratory rate to increase (tachypnea) to attempt to normalize the pH of the blood.
Autonomic centers that control blood pressure heart rate and digestion are located in the?
medulla oblongata
What are the Chemical receptors that regulates unconscious breathing?
The respiratory centers that control your rate of breathing are in the brainstem or medulla.Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers.Peripheral chemoreceptors also monitor the carbon dioxide concentration in the blood. In addition, a central chemoreceptor in the medulla monitors the carbon dioxide concentration in the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord; carbon dioxide diffuses easily into the CSF from the blood. If the carbon dioxide concentration gets too high, then both types of chemoreceptors signal the respiratory centers to increase the rate and depth of breathingThe peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF.

Name the respiratory pigment of blood in mammals?
Haemoglobin is the respiratory pigmaent of blood in mammals
What organization monitors blood borne pathogens?
OSHA -- Ocupational Safety and Health Administration and CDC -- Centers for Disease Control and Safety
What are the vital centers for control of heart rate respiration and blood pressure located in?
Medulla Oblongata
Where are the vital centers located?
There are three vital centers in the medulla which control the heartbeat, the rate of breathing, andthe diameter of the blood vessels. Centers that help coordinate swallowing, vomiting, hiccoughing,coughing, and sneezing are also located in the medulla.
Which part of the brain keeps the heart and crontrols breathing?
The respiratory centers that control your rate of breathing are in the brainstem or medulla.Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers.Peripheral chemoreceptors also monitor the carbon dioxide concentration in the blood.

The peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF.
Why is the medulla the most vital part of the brain?
It contains centers that control heart rate, blood pressure, breathing, swallowing (and vomiting), among others.
