Human gametes are oogamous.
Oogamous is a form of anisogamy which best describes human gametes. Oogamous is characterized by the joining of a large, immobile egg and a small, mobile sperm for reproduction. The male gametes are extremely motile and they are usually responsible for the joining of the corresponding gametes. The wide extension of oogamy in higher animals brings about the conclusion that the high motility of the gametes makes them to perform their respective roles better than it could be performed by general isogametes
Answer:
a high cardiac output and high peripheral resistance
Explanation:
Two factors affect the strength of the blood and consequently the blood pressure: cardiac output and peripheral resistance.
Blood pressure is determined by the product of cardiac output and peripheral vascular resistance. In normal individuals there is a spectrum of variation in cardiac output with concomitant peripheral resistance responses for a given blood pressure level. However, increased heart rate results in increased cardiac output, which increases blood pressure, leading to hypertension.
Answer:
The endometrial lining is shed during menstruation and is then regenerated by the hormone estrogen.
Explanation:
The menstrual cycle can be described in terms of:
1. <u>OVARIAN cycle</u>: divided into
-Follicular phase of variable length lasting between 7 and 21 days.
-Ovulation
-Luteal phase which is fairly constant and lasts between 12 and 16 days.
The most common cycle length is 28 days and this occurs in 15% of women in their reproductive age
.
The duration of flow is between 2-6 days.
2. <u>ENDOMETRIAL cycle</u>: divided into
-Proliferative phase where there is increase in growth of the functional layer and the endometrial glands under the influence of oestrogen.
-Secretory phase where endometrial changes are influenced by progesterone activity.
The endometrium is made up of the basal layer and the functional layer.
The basal layer remains intact throughout the cycle while the functional layer is shed during each menstruation.
