Question

4. Briefly describe and compare sinusoids and fenestrated capillaries with continuous capillaries. Give one specific organ where you would find these types of capillaries and describe their role in the organs in which they are present. Sinusoids: Fenestrated capillaries: B. Measurement of blood pressure and pulse rate 1. Under normal conditions, blood pressure in an artery oscillates from a high of_ mm of Hg called the pressure to a low of mm of Hg called the pressure. 2. Enter your results from the blood pressure measurements in the table below. Calculate the pulse pressures and the average values for each column. Students Systolic Pressure Diastolic Pressure Pulse Pressure (mm Hg) (mm Hg) (mm Hg) - 2 Average 3. Complete the following table comparing the pulse rate and blood pressure values at rest with those measured immediately after exercise and five minutes after exercise. At rest values from Immediately after Five minutes after previous table) exercise exercise Pulse rate (beats/min) Systolic blood pressure (mm Hg) Diastolic blood pressure (mm Hg) Pulse pressure (mm Hg) 4. Describe what happens to the BP and pulse rate after exercise

Answer 1

Sinusoid	fenestrated capillaries
Small irregular shaped blood vessels in liver	Fine branching blood vessels that connects arteries and venules
Have a discontinuous basal lamina	Have a basal lamina formed by endothelial cells
Open pores are present	Pores covered by diaphragm
Organ is liver	Present in glomerulus

B 1.. 120mmhg called systolic pressure

80mmhgcalled systolic pressure

2.

	Sbp	Dbp	Pulse pressure
1.	120	80	40
2.	130	90	40
3.	110	70	40
4.	140	90	50
Average	125	82	43

3.

	At rest	Immediately after exercise	5mins after excercise
Pulse rate	75	88	82
Sbp	125	140	135
Dbp	82	90	86
Pp	43	50	49

4.both heart rate and blood pressure is increased after exercise
