While blood is moving throughout the body, it distributes heat produced by the muscles . Blood transports nutrients and oxygen to the cells and removes their waste molecules, including carbon dioxide . The blood is also a route by which cells of the immune distributed throughout the body. system, such as lymphocytes, can be The nervous system consists of the brain, spinal cord, and associated nerves. The nerves conduct impulses from sensory receptors to the brain and spinal cord where integration occurs. Nerves also conduct impulses from the brain and spinal cord to the bones to respond to both external and internal stimuli. and glands, allowing us The endocrine system includes a number of glands, all of which secrete chemical messengers called hormones . These hormones have a wide range of effects, including regulating cellular metabolism, regulating fluid and pH balance, and regulating the glucose concentration of the blood. All organ systems are ultimately involved in maintaining homeostasis , or the stability of the body's internal environment. While regulating internal variables is energetically expensive, it is evolutionarily beneficial allows that organism to adapt to many different environments. Control systems like the nervous and endocrine the body's other systems. The skeletal as it systems coordinate and regulate the functions of and muscular systems protect the body and are involved in motor activity. The transport systems, specifically the cardiovascular materials to circulate through the body. and lymphatic systems, allow necessary The digestive, respiratory, and urinary systems are maintenance systems that provide nutrients and remove detrimental substances from the body. Homeostasis II Homeostasis can best be described as the body's Multiple Choice   ability to avoid responding to external stimuli. need to speed things up to a more energized state. need to slow things down to a more relaxed state.  ability to maintain constant internal conditions.  Sensory detectors During the maintenance of homeostasis, changes in bodily functions are detected by sensors, which in most cases are rev: 09_26_2019_QC_CS-182856 Multiple Choice  specialized sensory neurons.Correct    melanocytes. adipose tissues. specialized epidermal receptors. Information integration Once the sensor detects the change in bodily function, the information is relayed to which part of the body? Multiple Choice the hypothalamus within the brainCorrect     the spinal column the thyroid gland within the neck the pituitary gland within the brain  In a negative feedback mechanism, the response directs the system to operate in a similar direction. For example, if an individual is cold, the negative feedback mechanism would direct the body to become colder.  Group startsTrue or False True , unselectedbutton,Incorrect  unavailable   False selected button,Correctunavailable Group ends Question 1 1/ 1pts Hemoglobin is in the:  none of the above   red blood cells   white blood cells   platelets   Question 2 1/ 1pts _________ defends our bodies from attack by invading microorganisms.  red blood cells   none of the above   white blood cells   platelets   IncorrectQuestion 3 0/ 1pts Which of the following is a function of blood?  defends the body against infections   repairs body tissues   all of the above are functions of blood   controls the body's pH   Question 4 1/ 1pts A person with type O blood has which antigens on its red blood cells?  neither antigens A or B   antigen B   antigens A and B   antigen A   IncorrectQuestion 5 0/ 1pts Which of the following are white blood cells that fight pathogens?  neutrophils   lymphocytes   macrophages   all of these are white blood cells that fight pathogens   IncorrectQuestion 6 0/ 1pts What is the purpose of the white blood cells?  it returns any fluid leaked from blood vessels into the bloodstream   all of the above   it defends the body against infections by bacteria, viruses, and other pathogens   it is a type of blood that carries oxygen   Question 7 1/ 1pts Which is the most common blood cell in the blood?  plasma   red blood cells   blue blood cells   white blood cells   Question 8 1/ 1pts Which of the following functions are white blood cells NOT responsible for?  getting rid of debris   attacking invading cells   carrying oxygen to other cells in the body   fighting viral infections   Question 9 1/ 1pts __________ blood cells in blood plasma carry oxygen.  White   Platelet   Red   Question 10 1/ 1pts Each red blood cell lives for only ___________ days.  130   150   120   110  Question 1 0/ 3pts What happens to the blood in the lungs?  oxygen-rich blood releases oxygen and picks up carbon dioxide   oxygen-poor blood releases oxygen and picks up carbon dioxide   oxygen-poor blood releases carbon dioxide and picks up oxygen   oxygen-rich blood releases carbon dioxide and picks up oxygen 
